Chapter 3, Problem 3.17QAP

Interpretation Introduction

Interpretation:

The algebraic relationship between the output and input voltage is to be determined for the given circuit.

Concept introduction:

Based on the given circuit, we have two inverting summing amplifier configuration. Generally, the output of an inverting summing amplifier for two inputs is given by

$v_0=-R_f\left(\frac{v_1}{R_1}+\frac{v_2}{R_2}\right)$, $R_f$ represents feedback resistance and $R_1\text{ and }{R}_2$ represent the resistance at the input terminals corresponding to the respective input voltages $v_1\text{ and }{v}_2$.
